STREET AN STATION INDICATOR.

SPECIFICATION forming part of Letters Patent No. 383,392, dated May 22,1888.

Application filed August 18, 1837. Serial No. 247,288.

To all whom it may concern:

Be it known that I, SAMUEL M. FRIEDE, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inStreet and Station Indicators, of which the following is a full, clear,and eX- act description, reference being had to the accompanyingdrawings, forming part of this specification, and in which- Figure I isa perspective view of a station and track with my operative bufier-postsin position to actuate the indicators on the cars. Fig. II is anenlarged perspective view of my buffer-post that operates thestation-indicator. Fig. III is an enlarged detail view,showing the crossbuffer-arm with the spring give-and-take plate to prevent injury fromtoo severe a concussion of the buffer-heads, showing also the butier-heads and the trigger-catch ready to re tire from the spring-pawland let the disk turn with the corresponding reels. Fig. 1V is a similarenlarged detail view of the buffer-arm when in its inoperatve position,the bufferheads turning on their hinges and allowing the train to passwithout shifting the indicator. Fig. V is an enlarged detail viewshowing the bufferheads with their return-springs on their pivot-pins.cross section of a case with my indicator attached, showing the pivotedtrigger-lever that lets'loose the disk for one revolution to change theindicator. Fig. VII is an enlarged back viewof the rolls, showing theindicator-scroll, the rollers that project it in prominent view of theoccupants of the car, and the handcrank that winds up both the scrolland the coilspring that automatically operates the scroll as it unwinds.Fig. VIII is an enlarged side viewof the trigger-disk and section of thescroll-roll, with part broken away to show the action of the spring-dog,which is in engagement with the trigger-lever before it is sprung. Fig.IX is a like view showing the trigger sprung, the disk rotating, and thescroll drawing out to reindicate the next station. Fig. X is an enlargedside view of the bracket that provides pivotal bearings for the triggerlever, showing also the spiral springs around the pivot-pin, that allowlateral movement of the trigger-lever on its bearings and return it Fig.VI is an enlarged (K0 model.)

again to its central normal position. Fig. XI is an enlarged transversesection, taken on line XI XI, Fig. XII, of one of the reel-shafts withits removable sleeve, which carries the scrollroll, and Fig. XII is anenlarged longitudinal section, taken on line XII XII, Fig. XI, of one ofthe reel-shafts and sleeves, showing also the key-pin that secures theattachment of the sleeve to the shaft. Fig. XIII is a longitudinal topview of a car, showing the bufferheads on the spring-attached extensionsof the crossarms of the bufferposts, the one in operative position inrelation to the moving car actuating the trigger-lever through itsbuffer-head to trip the indicator device, and the other, when ininoperative position, allowing the corresponding buffer-heads to passeach other with out tripping the trigger-lever.

This invention relates to devices for indicating to passengers ofrailway-ears the next street or station at which the train stops; andthe invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Referring-to the drawings, in which similar figures of referenceindicate like parts in all the views, 1 represents the sleepers on whichthe rails 2 rest, 3 the bufferpost, which, with its braces 4, rests onelongated bedsleepers 5 of the track, so that the posts are invariablyleveled to correspond with the level of the track, and should frost orother causes vary the level of the one it will operate alike on theother also, to make the buffer-heads on the cars and posts maintaintheir correlative positions.

6 is the buffer crossarrn that projects at a right angle from the post,and is supported at said angle by the brace 7. The said cross-arrn iscut at 8, providing an extension, 9, that is reunited by a spring-plate,10, at its back, which is secured to said extension and the maincross-arm by screw-bolts and nuts 11.

12 is the hinge-plate secured by screws or bolts to the extension 9, andprovided with loops 13, in which the pivot-pin 14 engages for theattachment of the buffer-head 15,which also has hinge-loops 16, throughwhich said pin engages. A return coil-spring, 17, surrounds thepivot-pin between the loops of the hinge-plate and buffer-head, andprojecting ends of the coil-spring press relatively against thehinge-plate and the shank 18 of the bufferhead to enforce the afterreturn action of said bufler-head to its normal position.

19 represents a car to which my invention is attached. 20 is theautomatically-operated reel-scroll indicator device, which is erected induplicate at each end of the car in the summit-dome 21 of the roof 22.

The reels 23 and scrolls 24, that carry the street and station names 25,are preferably secured within an inclosed chamber, 26, which isduplicated at each end of the car. Said chamberisprovidedwithadrop-sash,27,thatis secured by hinges 28 to the cap 29 at the topsof the openings 30 into said chamber that the sash closes. Thesash-frame surrounds a glass plate, 31, that allows afree view to thepassengers of the names of the next street or station on theindicator-scroll.

The reel-shafts 32 run within hearings in the frame 33, and the reelsare provided with sleeves 34, that are rigidly secured to the disks 35of said reels (and fit around said shafts, to which they are secured) bykey-pins 36. The shafts of the reels have their bearings in the frame ata suitable distance apart to most advantageously exhibit the name of thestreet or station. One of the reel-shafts has rigidly secured to it apinion-wheel, 37, that engages in a gear-wheel, 38, on a shaft, 39, thathas bearings in the frame 33 back of the said reel-shaft. The shaft 39has one end of the coil-spring 40 secured to it and wound around it, ashereinafter described. The other end of the spring is firmly securedaround the screw-bolt or lug 41, that is secured to one of the side barsof the frame at 42.

The indicatorscr'oll is preferably made of fine linen or other strongand preferably glazed material, and has clearly delineated on it inrelative succession and by any suitable means the names of the streetsor stations at which the cars stop. The ends of the scroll are eachsecured by any suitable means to the sleeves 34, that surround and arekeyed to the reelshafts. A hand-knob, 43, is rigidly secured to the oneof the reel-shafts that is next to the main eoil-spring 40, and acrank-handle, 44, is also rigidly secured to the other reel-shaft.

Adisk, 45, is keyed or otherwise rigidly secured to the sleeve 34 on thecrank-handle reel-shaft. A dog-pawl, 46, having bifurcated arms 47, thatembrace the disk, is secured thereto by the pivot-pin 48 on which itturns, but is limited in its outward movement by the stop-pin 49 at itsreverse end on the side of the disk. The dog-pawl is projected to itsoperative position by the spring 50, except when pressed back on itsinoperative curved side, when it bends the spring and retires under theinfluence of the pressure.

51 represents the trigger-lever, which works in the annular recess 52 ofthe double diskcap 53, that is secured to the stud 54 and side piece ofthe frame 33 by the screw-threaded pivot-pin 55, on which the leverworks. Said trigger-lever has a catch-hook, 56, integral with the mainarm of the lever, which engages with the dog-pawl 46 and keeps thescroll from unwinding until the trigger-lever is tripped, and a shortbalance-hook, 57, reaches out in an opposite direction and stops thedog-pawl in its rotation, should the trigger-lever, from any accidentalcause, not return the hook 56 in time to stay a second rotation of thedisk and dog-pawl. The outer end of the triggerlever works within anelongated bracket, 58, that is secured near the caves of the roof of andto the car. The lever has lateral movement along a pin or rod, 59, thatpasses through a slot, 69, therein, and the rod is riveted orscrew-nutted at each end at 60 to the bracket. Spiral springs 61 aroundthe belt at each side of the trigger-lever allow it to move freely underthe pressure of the buffer-heads a sufficient distance to trip thetrigger; when released from the pawl-dog the springs quickly return itto its central normal position. On the outer end of the trigger-lever isa similar hinge-plate, 12, to that described on the extension ofthebuffer crossarm and similarly secured to the trigger-lever as that is tothe said extension 9, with similar buffer head hinge-loops on bothhinge-plate and shank of buffer-head, also hinge pivot-pins andreturnaction coil-springs,which are duplicates of the said parts on thesaid cross-arm of the bufferpost and .are also indicated by duplicatenum' bers. The two buffer-heads act in correspondence with each other,bot-h when inoperative and when operative. They move freely on theirhinges on coming in contact with each other, so as to pass withouttripping the trigger when the car or train isbacking or moving in areverse direction to that the indicator is required to work, and theirsprings afterward bring them back to their normal posi.

tion, ready for service when the car is again moving in its usualdirection in relation to the buffer-posts, with which the buffer of thetrigger-lever is then intended to engage, at which time (when operative)the buffer-heads are as far back on their hinges as they can turn andthe shoulders of the lugs 62 at the back of the hinge-joint braceagainst each other and re-enforce the hinges to withstand theback-pressure caused by contact of the buffer-heads, which, inconsequence, trip the trigger-lever, allowing the scroll-reel to makeone revolution and so change the street or station record visible on thescroll to that of the next stop.

Two vertical shafts, 63, that have bearings at 64 in the frame 33, carryanti-friction rollerreels 65, that convey round the part of theindicator-scroll that next exhibits the name close to the glass in thesash 27, through which itis shown.

Preparatory to running the scroll at first around the reel next themainspring by the hand-knob 43, (which operation is alone required whenthe indicator is first set up in the car,) the pinion-wheel 37 isunshipped from the shaft of said reel to allow said reel to turn freelywithout keeping up its geared connections with the adjacent mainspring.At such time the stop-pin 66 is projected through a perforation, 67, inthe frame 33 until it engages between the cogs of the gear-wheel 38 andlocks it from turning, the said cogs also by their clutch-hold of thepin preventing its withdrawal. When the piniolrwheel is rein.- stated, amovement of the crank-handle of the reels will loosen the hold on thepin, and the spiral spring 68 around said pin withdraws the same fromobstruction.

The operation of the invention is as follows: The reel'shaft 32 next themainspring 40 is turned by the hand-knob 43 until as much of theindicator-scroll is wound thereon as its mutual connection with thecorresponding reel will allow. The pin-key 86, that secures the sleeve34 to the first-mentioned reelshaft, is then removed to allow thepartial withdrawal of the shaft in its sleeve sufficiently to ship thepinion-wheel 37 on the other end of the shaft, so that as the shaft isturned to its bearing in the frame the pinion-wheel engagesin thegearwheel 38 on the shaft that carries the mainspring 40. The key-pin 36is then returned to its seat. The crank-arm 44 of the other scroll-reelshaft is then turned until the scroll is wound onto the reel secured toit in as far as its mutual attachment to the corresponding reel willallow, which leaves open to view the name of the street or station fromwhich the car or train starts. It will be seen that as the scroll iswound by the hand-crauk onto the reel it turns, the withdrawal of thescroll from the other reel turns it and the pinion'wheel on its shaft,thereby turning the gear-wheel 88, with which itengages, which throughits shaft winds the mainspring that it also carries. At the same timethe dog-pawl 46 on the disk 45, that is carried on the same shaft thatthe crank turns, is engaged by a claw on the inner end of the pivotedtrigger-lever 51, which claw is tripped clear of the pawl when thebufferhead on the end of said lever comes in contact with thebuffer-head on the cross-arm of the post 3, allowing the disk 45 thatcarries said pawl and its accompanying reel to make one rotation underthe influence of the mainspring and withdraw that much of the scrollfrom the crank-shaft reel and exhibit the name of the next street orstation at which the car will stop. The scroll is of sufiicient lengthto carry the names of all the streets or stations on the line. On thereturn trip the indicator at the reverse end of the car, which thenbecomes the forward end, comes into operation, and the bufferheads ofits trigger-lever (which on the last trip freely turned on their hingesto pass in their inoperative position the bufferheads of the posts) nowcome into operative position, and, being reverse duplicatesin posit-ionof the indicator at the other end of the car, it indicates consecutivelythe names of the streets or stations next ahead.

It will be understood that, as shown in Fig.

XIII, the buffer-posts and the pivoted triggerlever with theircorresponding buffer-heads that are on the right-hand side of the car asit faces are always operative, while those on the left-hand side arealways inoperative, and the then loose hinges of the buffer-heads allowtheir free and inoperative passage; but when the car returns on the sameor aparallel track, what was before the left-hand inoperative sidebecomes the right-hand operative side and operates the scroll-reels onthe other end of the car, which, for the time being, becomes the frontend of said car.

lVith the exception of rewinding the scrolls, and in consequence themain coil-spring, by the handcrank 44 at each end of the line, theinvention is entirely automatic in its action, and,unless a car hasinadvertently been turned end for end at any time when placing on thetrack,will continue to so work ad infim'imn as long as the material ofwhich it is constructed will last.

As heretofore described, when a car has been misplaced end for end, allthat is required to effect a perfect reorganization of the parts is toextract the keypins 36 and unship the reels, scrolls, and theiraccompanying sleeve-tubes, pinion-whecls, disks 45, and dog pawls,whichare readily removed together, and transfer them vice versa to thereverse ends, when the consecutive rotation of the indicated names onthe scroll and all its connected devices will be found in working order,the same as when operated at the reverse end of the car.

The trigger-lever and its attached bufferhead is always in rightposition, whichever way the car is either placed or misplaced,and sorequires no transference.

I claim as my invention- 1. In a street and station indicator forrailway-cars, the combination, with the indicator proper and itstrigger-lever, of a suitablymounted arm projecting toward the side ofthe track from the car, an extension having spring-connection at oneside therewith, a buffer-head h'aving pivotal connection with the endofsaid extension on its opposite side, and a spring surrounding thepivot-connection, its ends bearing respectively on the bufferhead andextension, substantially as set forth.
